So the greatest common factor 87,33,639 is 3.
Lets's calculate LCM of 510,391,677
17 | 510, 391, 677 |
30, 23, 677 |
∴ So the LCM of the given numbers is 17 x 30 x 23 x 677 = 7941210
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/7941210
Therefore, the GCF of Fractions 87/510,33/391,639/677 is 3/7941210
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 510,391,677 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(510,391,677) = 1
common factors(in case of two or more numbers have common factors) = 17
GCF(510,391,677) x common factors =1 x 17 = 17
LCM(510,391,677) = ( 510 × 391 × 677 ) / 17
LCM(510,391,677) = 135000570 / 17
LCM(510,391,677) = 7941210
